2 '0 all whom it may concrn: lie it known that I, Fnmmmcn R. Conuwann, a citizen of the United States, residing atStLouis, Missouri, have invented a cerlaln new and useful Improvement in Fourth- Point Supports for Brake-Remus, of which the following is a full, clear, and exact description, such as will enable others skilled III the art. to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of thisspocification, in which ."ElglllG 1 is a plan, view of abrake beam .hoy'vingnw improved fourth-point support 16. nrraiigedt iereon'. a

I-Ieretofore, so far as I am aware, fourth point supports for brake beams have been made in pairs, that is,

different patterns have been used for the fourth point supports which are a plied at opposite ends of the beams, usual y designoted as the right and lefthand end of the beam.

The object ofmy present invention is to enable the use of a singlepattern for fourth point supports eapeblo'oi use or attachment to 'opposite ends of the beam thereby timing the original 'eostand nuinber of parts necessary to beeei'ried inrepair shops];

to clamp the loop 8 in position, it' will cause said loop to tightly clamp the saddle member onto the tension member.

10 indicates a rubbing or hearing shoe (see Fig. 6) which is provided with openings 10" designed to register respectively with diagonally disposed openings 7" on the wings 7 depending; upon whether the wearing shoe is to be used at the right or lefthand. side of the beam. The wings 7 are spaced apart sutliciently at the middle so as to permit. the upper cross member of the Shoe 1.0 to be placed in position above the wings and then by a turning movement located over the wings so as to register the openings 10 with the diagonally disposed openings 7", depending upon which end the beam or shoe is used in which cotter pins 11 are passed through the registering openin to hold the shoe in position.

%he construction shown in Figs. 7 and 8 is substantially the same as that disclosed in Figs. 1 to 6, except that the wings 7 are connected by a bridge member 7 and the wearingshoe 10 has its top wall cut away as at" 10" so that it may be. assembled frombeneath the bridge 7' passing through this opening after which the wearing shoe is turned to the desired osition;

In Figs. 9 to 12, inclusive, the saddle member has two end extensions 7 for receiving the clamping loo s 8", therebeing a connoctingbar 7" s ace from the tension member 4 and rovi ed with a pivot pin 7 atitscenter. be wearing or rubbing shoe 10 is substantially-the same in this form as is shown in Figs. 1 .th ,6, except that it is provided with a medial opening 10: to receive the pivot pin 7"; In assembling the parts of this form of my jl'lVBLlClOIl, the end of the saddle member is through the opening of the shoe mom or and the pins 7" located in the openings 10. The clamping members '8 are now arranged in position to clamp the saddle' member, after which the shoe is adjusted to its desired position and the cotter pins 11" passed through the registering openings, as before described, for the purpose of holding the shoe in its proper angular relation to the saddle member.

In 13 and 14, I have shown a form of my invention in which there is a space between the wings of the saddle member and also .an opening in the upper cross bar of or axle of the roller-12.

brake beams comprising to be secured to a part of the brake beam, at

with respect to in combination lhe reversible member 10 in this form is provided with perforated ears or lugs at each end in winch is mounted the journal This roller thus forms an anti-frictional reversible fourth point support.

What I claim is:

1. A reversible fourth point support for brake beams comprising a member designed to be secured to t e brake beam, and a bearing member havin an' angular adjustment with respect to 53.1 first-mentioned member.

2. A reversible fourth point support for bearing member having angular adjustn'ient said first-mentioned 'member, and means for holding. member in its adjusted position;

3. A fourth point su port for brake beams comprising a member. esig'nod to be secured to-a part of the brake beam, in combination with a detachable bearing member supported upon said first-mentioned member and capable of angular adjustment relative thereto. 4. A reversible fourth point support for brake beams comprising a member designed to be secured to a part of the brake beam,

which may be turned with relation to said first-mentioned member so as 'ito adapt it for use at either end of thcbeam.

5. A fourth point support for brakebeams comprising a member adapted to be secured to a part of the brake beam, in combination with a bearing member detachably mounted with relation to said first-mentioned mem her and angularly adjustable with respect thereto, and means for locking said bearing member in adjusted position;
